Notes:

The source code for Arasan includes optional support for both Gaviota and Nalimov tablebases. Nalimov tablebase support requires use of the egtb.cpp file, which is copyrighted by Eugene Nalimov, and the tbdecode.h file, copyrighted by Andrew Katatch. These files are no longer distributed with the Arasan source. However, Arasan binaries provided by Jon Dart include the Nalimov tablebase support.

Gaviota tablebase probing code is available separately, under the same license used by the Arasan chess engine, from Miguel Ballicora or from arasanchess.org.

The Arasan user interface, source of which is in the "gui" directory of the Windows source archive, relies on copyrighted chess fonts and is not included under this license.

The Arasan Windows GUI (binary and source) and Arasan chess engine binaries from Jon Dart may be freely distributed, provided that:

1. They are distributed in unmodified form.
2. No more than a nominal fee is charged for copying or media.
